JOSEPH DALTON, OF BROOKLYN, E. D., NEW YORK.

Specification forming part of Letters Patent No. 44,403, dated September27, 1864.

To all whom it may concern.-

Be it known that I, JOSEPH DAL'roN, of Brooklyn, E. D., county of Kingsand State of N ewYork, have invented a new and use ful Improvement inKnittingdvlachines; and I do hereby declare that the following is a`full, clear, and exact description thereof,

make and use the same, reference being had t-o the accompanyingdrawings, forming part of this specifica-tion, in which- Figure 1represents a -vertical central section of this invention, the plane ofsection being indicated by the line a' w, Fig. 2. Fig. 2 is a plan ortop view of the same.

Similar letters of reference indicate corresponding parts.

r1his invention relates to certain improvements in that class ofmachines which are known as Daltons KuittingMachines, and in which acylinder of stationary needles is used with the barbs on the outside, asshown in my patent of May 7,1861. Within this Y cylinder rotates a shaftin unison with a circular table revolving around the cylinder ofneedles, so that the respective burr-wheels, carried within the cylinderof needles by the shaft, and outside thereof by the circular table,travel around the said cylinder of needles and deposit the yarn in thebarbs of the needles, close the said barbs, cast oit' the previous loop,and thus knit the fabric by any of the well-known character of stitches.

This present improvement consists in casting the needle-cylinder solidwith the bcd or stand of the machine, so as to save a large amount ofstock and of labor requisite with the present arrangement in use priorto this my invention in fitting and securing the cylinder to the bed 5also, in ruiming' the revolving circular table between the flange of thecylinder and the needle-plates, and thereby dispensing with theoldstationary bed, with the hub of the cylinder, and with the nutrequired to hold the same in its place, further, in the use of anadjustable collar, in combination with the revolving` table andneedlecylinder, in such a manner that any wear in the working-surfacesof the cylinder or table can be compensated -for at any moment, and theburrs are enabled to retain their relative i distance from the needles.Finally, in making the needle-plates adjustable in a vertical direction,so that the same can be readily arranged to bear uniformly upon theinner edge ring in the bearing-surfaces can be compensated for withlittle trouble or loss of time.

A represents the bed or stand, which is cast solid with the cylinder Band with the l legs C. lhe bed A is perforated in the cenl ter toreceive the inner shaft, and it extends l beyond the cylinder, forming aange which supports the revolving table D, as clearly shown in Fig. 1 ofthe drawings. The ta le I) is revolved by suitable bevelgear from thedriving-shaft, which is not represented in the drawings, and itisprovided with a ring or collar, E, the inner circumference of whichbears against the cylinder A. Said collar is made in two or moresections, which are secured to the table by a series of screws, a, andbetween the adjoining ends ofthe several sections of the collar smallgaps b are left, so that in case of wear said sections can be closed up.The holes through which the screws pass are oblong slots c, madeparallel to each other when but two sections are used, but radial withthe axis when more than two sections are used, so that the severalsections of the collar can be adjusted toward or from the center of thecylinder as may be desirable. By this arrangement any wear in thebearing-surfaces of the table and cylinder can be readily compensatedfor, and the gears arc enabled to retain their relative distance fromthe needles with perfect accuracy. The table D revolves between theflange of the cylinderB and the needle-plates F, which are secured tothe outer circumference of the cylinder by screws d. rlhe holes in theplates through which these screws pass form oblong slots c, (see Fig.1,) arranged so that said plates can be adjusted up and down, and thattheir lower edges can be kept close to the upper surface of the collar.By this arrangement the bearingsurfaces of the principal parts of mymachine can be readily adjusted,

i of the revolving table, and any wear occur-v which will enable thoseskilled in the art to and the machine can be kept in perfect; worki incombination with the revolvingtnble D ing'order fonany length of time.

I claim as new and desire to secure by Letters Patentl. Casting thel'leedle-eylinder ofaknittingmaelline solid with the bed or stand.

2. Running the revolving table D between the flange of the cylinder BIand the needleplates F, substantially as and for the purpose specified.

3. The adjustable sectional eollarE, applied i and cylinder B, in themanner and for the pur-- pose substantially as herein shown anddescribed.

4. Making the needle-plates vertically adjustable, for the purpose setforth.
